| titleOfInvention | Additive for vitrification treatment of incineration fly ash and method for vitrification treatment of incineration fly ash |
| abstract | The invention provides an additive for vitrification treatment of incineration fly ash, which comprises the following components in parts by weight: 5-60 parts of SiO 2 1-10 parts of H 3 BO 3 1-10 parts of carbonate and 1-5 parts of nitrate. SiO 2 2 And H 3 BO 3 The fly ash and the incineration fly ash form a network structure to stabilize heavy metal ions, carbonate and nitrate are used as a clarifying agent and a fluxing agent to be beneficial to forming a compact melting system, and all components synergistically act to improve the immobilization degree of the incineration fly ash and reduce the vitrification treatment temperature. The invention also provides a method for vitrifying incineration fly ash, which sequentially comprises the following steps: (1) providing an incineration fly ash sample and the additive for vitrification treatment of incineration fly ash; (2) preparing a mixture of an incineration fly ash sample and an additive for vitrification treatment of incineration fly ash, drying, mixing and granulating; (3) putting the mixture into a plasma melting furnace for melting treatment; (4) and after the molten slag is completely melted, cooling to obtain the glassy state slag. The method improves the solidification rate of heavy metal, greatly reduces the volume of the incineration fly ash and protects the environment. |
